Slowing The Gui Down In Android

My Android App works fine, except the end sequence. Its a game and at the end the screen shows the score: TextView allscores = new TextView(this); allscores.setText('Your score: '

Solution 1:

You're not seeing the score because sleeping on the UI thread prevents the layout and drawing operations that make your text changes visible. Never sleep on the UI thread.

Using a new thread for this is overkill. Use a Handler and the postDelayed method to make something happen after a delay.

privatefinalHandlermHandler=newHandler();

Then when you want to do something later,

mHandler.postDelayed(new Runnable() {
    publicvoidrun() {
        doDelayedThing();
    }
}, 3000);

Solution 2:

As others have pointed out: don't use sleep in the UI thread.

What you should do instead is described here:

http://developer.android.com/guide/appendix/faq/commontasks.html#threading

in section "Handling Expensive Operations in the UI Thread"

Solution 3:

It is not recommended to ever sleep the main UI thread. Try something like this:

new Thread(new Runnable(){ //do work here });

Or you could try using a Toast popup for the score.

Solution 4:

You can also use Timer to wait 3 seconds, which will start a new thread after the time runs out.

Timertimer=newTimer();
timer.schedule(newTimerTask() {
    @Overridepublicvoidrun() {
                AnViewanimator=newAnView(this);
                layout.addView(animator);
    }
}, 3000);
